Sandy brought 6.67 inches of rain to Baltimore-Washington International Thurgood Marshall Airport from Oct. 28-30. (The rain was heavier on the Eastern Shore, however, where many areas saw as much as 12 inches, including the town of Bellevue, which saw 12.83 inches, more rain than anywhere else during the historic storm.)

To compare an equal period of time, 6.42 inches fell at BWI from Thursday through Saturday. Rain was also measured Wednesday at the airport, 0.07 inches.

In a normal October, 3.33 inches of rain falls at BWI, while the record for the wettest October in Baltimore is 9.23 inches set in 2005.

That erases concerns of a developing drought. According to the U.S. Drought Monitor, 70 percent of Maryland, including all of the Baltimore region except Harford County, was considered "abnormally dry" as of Tuesday, but that is likely to shrink or disappear when the map is updated with the next week of data, to be released Thursday.

According to National Weather Service models of the precipitation that fell across the state over the past week, the heaviest rainfall was in the western suburbs of Baltimore, including parts of northern Anne Arundel County, western Baltimore County and Carroll and Howard counties. Rainfall totals are estimated in the range of 6-8 inches.

Historic flooding and the coldest temperatures in decades made weather headlines in Baltimore in 2014. Rainfall records were set in April and August, and after a frigid winter, the summer was comfortable and fall cool. The year is expected to be the coolest and wettest here in years.
